What’s a good hard drive recovery software?
My external hard drive died out of nowhere. I plugged it as usual and it didn’t detect. So I disassembled the external and installed that hard drive into the desktop. When I boot up into windows it detects the hard drive but it shows as an unallocated drive.
Is there any software (free or for purchase) that will allow me to see my data?
You can try to recover your files from external HDD with Easy Drive Data Recovery software:

It uses unique modern algorithms to recover files that other software either recovers incorrectly or is unable to detect.
TestDisk is pretty good. It is a free data recovery software that can run on multiple operating systems, which includes Windows, Mac, and Linux.
